Validating and assign variables in ant

All,

I think I send this before but unfortunately, no answers yet. So here I go 
again...

Can I validate and then assign values to properties in ant just like any shell 
scripts would?

Here is what I am trying to do:

      <property name="catalina.home" value="${system.CATALINA_HOME}"/>
      <property name="appserver.home" value="${system.JBOSS_DIST}"/>

As you can see, when the environment variable is not set, catalina.home will 
always be assigned to a string "${system.CATALINA_HOME}. What is the correct 
way to do it? 

Thanks

Barry

Posted by didge <di...@foundrylogic.com>.
Have you tried <fail>?

For example:
<fail message="CATALINA_HOME must be set" unless="${env.CATALINA_HOME}/>
